Description

[0001] The utility model relates to the technical field of composite foundations, in particular to a highway composite foundation structure. Background Art

[0002] The highway composite foundation structure is an artificial foundation formed by reinforcement treatment on a weak foundation, aiming to improve bearing capacity and reduce settlement. This structure is widely used in the construction of roads, bridges and other transportation infrastructure, and has significant engineering benefits and stability.

[0003] In the existing technology, some highway composite foundation structures are achieved by setting reinforcement bodies in weak foundations to form artificial foundations in which the foundation soil and vertical reinforcement bodies jointly bear the load, thereby improving the bearing capacity and reducing settlement. During the settlement process, the fixed piles will become unstable, causing the fixed piles to fall off. However, during actual use, the fixed piles cannot be reinforced. The unreinforced fixed piles are difficult to effectively disperse the load, resulting in stress concentration in specific areas, increasing the risk of damage to the pile body and the surrounding soil. Therefore, in response to the above problems, a highway composite foundation structure is proposed. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The present invention provides an embodiment of a composite highway foundation structure, comprising a base layer 1, which serves as the foundation of the entire composite foundation. Base layer 1 is typically composed of compacted earth and rock, and is flat and wide, providing a solid support platform for the superstructure. Multiple fixed piles 2 are fixedly connected to the top of base layer 1. These piles are typically cylindrical and made of reinforced concrete. These piles are deeply embedded in the ground, enhancing the stability of the entire structure. The outside of the fixed pile 2 is fixedly connected with a reinforcing rib 3, which is also made of steel bars and has a slender and curved shape to adapt to different mechanical requirements. The outside of the reinforcing rib 3 is fixedly connected with a fixing component for support. The fixing component includes two connecting plates 4, which are usually made of steel plates and have a rectangular shape and are vertically connected to the reinforcing rib 3. The outside of the connecting plate 4 is fixedly connected with a rivet 5. The outside of the rivet 5 is fixedly connected with a limiting ring 6. The rivet 5 is made of high-strength steel, and the limiting ring 6 ensures a tight connection between the connecting plate 4 and the reinforcing rib 3 to prevent any relative movement. The outside of the connecting plate 4 is fixedly connected to the outside of the reinforcing rib 3. The adjacent sides of the two reinforcing ribs 3 are fixedly connected with a reinforcing plate 7. The outside of the reinforcing rib 3 is fixedly connected with a reinforcement plate 8. The reinforcing plates 7 and 8 are both made of thickened steel and their shapes are designed according to actual needs to provide additional rigidity and support.

[0032] The exterior of the reinforcing rib 3 is provided with a plurality of slots 10. The exterior top of the fixed pile 2 is fixedly connected to a reinforcing frame 9, which is made of steel or alloy material and is used to disperse pressure from the upper layer. A reinforcing layer 15 is provided inside the base layer 1. A buffer layer 14 is provided on top of the reinforcing layer 15. The exterior of the buffer layer 14 is provided inside the base layer 1. The buffer layer 14 is made of geotextile, which has excellent tensile strength and durability and can effectively absorb and disperse pressure. A concrete layer 13 is provided on top of the buffer layer 14. The concrete layer 13 is made of fiber-reinforced concrete and has excellent compressive strength and crack resistance. The exterior of the concrete layer 13 is provided inside the base layer 1. The concrete layer 13 is made of fiber-reinforced concrete, which not only has high compressive strength, but also has internal fiber materials that increase its crack resistance, making the entire structure more solid and durable.

[0033] Reference Figures 3 and 4 A crushed stone layer 12 is provided on top of the concrete layer 13. Broken bricks are the main material of the crushed stone layer 12. They have good drainage and air permeability, and can effectively prevent moisture from accumulating in the base layer 1, thereby reducing water erosion and freeze-thaw damage. The crushed stone layer 12 is in the shape of irregular fragments, which helps to increase its friction with the upper sand cushion layer 11 and improve the overall stability. The outside of the crushed stone layer 12 is set inside the base layer 1. Setting the crushed stone layer 12 inside the base layer 1 can ensure that it plays the best drainage and support role in the entire structure. The contact area between the crushed stone layer 12 and the base layer 1 is large, which is conducive to dispersing the pressure transmitted from the upper layer and promoting the drainage of groundwater through the porous structure of the crushed stone layer 12. The material of the crushed stone layer 12 is broken bricks;

[0034] A sand cushion layer 11 is located on top of the gravel layer 12. This layer is made of naturally graded sand and gravel. This type of sand and gravel has excellent load-bearing capacity and compactness, further enhancing the stability of the structure. The sand cushion layer 11 is typically shaped like uniform sand particles, effectively filling the gaps in the gravel layer 12, reducing the weight of the superstructure directly acting on the gravel layer 12 and minimizing the migration and rearrangement of the gravel. The exterior of the sand cushion layer 11 is located within the base layer 1. The combination of the sand cushion layer 11 and the base layer 1 allows the entire composite foundation structure to better distribute pressure when subjected to stress, reducing localized stress concentrations. Furthermore, the sand cushion layer 11 serves as a buffer layer, mitigating the impact of environmental changes on the base layer 1. The sand cushion layer 11 is made of naturally graded sand and gravel. The exterior of the reinforcement bar 3 is fixedly connected to the interior of the retaining groove 10. The retaining groove 10 connects the reinforcement bar 3 to the fixing pile 2, the reinforcement frame 9, and other structures. These retaining grooves 10 are located on the exterior of the reinforcement bar 3 to precisely secure and adjust the position of the reinforcement bar 3. The design of the slots 10 ensures that the reinforcing ribs 3 maintain their position when subjected to external forces, thereby improving the reliability and durability of the entire structure. The reinforcement layer 15 is made of reinforced concrete. As a crucial component of the entire composite foundation structure, reinforced concrete is chosen to ensure sufficient load-bearing capacity and resistance to deformation. Reinforced concrete not only provides strong compressive strength, but the internal steel bars also enhance its performance under tension, making the entire structure more stable against surface and underground movement.

[0035] Working Principle: First, the base layer 1, composed of compacted soil and rock, serves as the foundation, providing a stable support platform. Fixed piles 2 are driven deep into the ground to enhance the stability of the structure and connected to the fixed components via reinforcing ribs 3, forming a solid support system. Connecting plates 4, rivets 5, and retaining rings 6 ensure the fixation and stability of the reinforcing ribs 3. These are further reinforced by reinforcing plates 8 and 7. The reinforcing ribs 3 are connected to the fixed piles 2 and reinforcement frame 9 via slots 10, dispersing pressure from the upper layers.

[0036] Inside the base layer 1, the reinforcement layer 15 provides additional bearing capacity, the geotextile material of the buffer layer 14 effectively absorbs and disperses pressure, the concrete layer 13 is located on the buffer layer 14, and fiber-reinforced concrete is used to improve compression and crack resistance. The gravel layer 12 is placed on the concrete layer 13, and crushed bricks are used as the main material. It has good drainage and air permeability, prevents moisture accumulation and reduces freeze-thaw damage. The sand cushion layer 11 is located on the gravel layer 12, and natural graded sand and gravel are used to further improve the stability and bearing capacity of the structure.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
